New vs old Shimano brifters
Have I got this right:
1 The new style 10 speed DuraAce/Ultegra Shimano brifters are the only ones compatible with the Flight Deck computer with altimeter? 2 The new style 10 speed DuraAce/Ultegra Shimano brifters are, for some reason, not compatible with FSA triple chain rings (or maybe any triples)? I've got the old style Ultegra brifters but have to run an altimeter in addition to my front Flight Deck, have mounted a Ciclo 434 on the rear top tube, for my stoker. Thanks, |

The crankset is pretty independent of the shifter and derailleur, and any crankset rated for 10-speed use should work fine. However, with a triple crankset, try to match the tooth difference between the large and middle rings to the tooth difference of the crankset from that series of components. For instance, 6600 and 6700 Ultegra uses 39 and 52 tooth rings on the triple crankset, whereas 5600 105 (and maybe also 5700, I don't know yet) uses 39 and 50 tooth rings on the triple. Using the non-matching front derailleur makes the vertical positioning a bit wrong, which can significantly affect performance. However, an Ultegra front derailleur with an FSA crankset that has 39/52 rings or 39/53 rings should be fine (just don't use a 105 FD with that setup because downshifts from middle to small ring will be a problem). If your goal is to have just one computer, but still have gear information and altitude information, then instead of changing your shifters and computer, then you could go with the setup that I use. My computer is a CicloMaster 4.3A, and so has full altimeter functions (which I find essential for our frequent rides in the Alps), plus I have an inline gear indicator mounted where the gear cable exits the brake/shifter unit. Just Google "Dura Ace inline gear indicator" and you'll find it, or your LBS probably has some sitting in a drawer. The red ring slides behind the plastic cover to tell you which gear you are in. They don't make one specifically designed for the front shifter, but you could install one on that side also - I have one labeled as a 9-speed XTR indicator that is the same but only has three sections marked on it that I've often thought about putting as a gear indicator for the front triple derailleur, but instead I now use a bar-end or thumb shifter for the front derailleur which has the two advantages of continuous control of the front derailleur (rather than indexed) and gives a visual indication of gear position based on the current angle of the level. These indicators don't work well with the new 7900/6700 levers because the under-the-bar-tape routing means that there is no good place to mount the indicator. The weight is just a few grams, and so a lot less than a flight deck computer (and they create a lot less clutter in your cockpit). http://bikeforums.net/attachment.php...hmentid=139640

The mechanic at my LBS told me that the new DuraAce/Ultegra brifters are not compatible with Flight Deck. I don't understand why Shimano would drop Flight Deck but it sounds like they have.

Chris_W,
Thanks for all this useful information. Are the Shimano Ultegra 6603 STI Triple 10 Sp, which I have at the moment still available? Or their Dura Ace equivalents, whatever they would be? I am thinking now that I will just order another set of these as they work with everything else on my setup. Thanks again. |
